Enertracting

Energy Service Companies (ESCO) have become pioneers in the development of financing and operating models for various energy sector customers. Every two years, the so-called Contracting Award highlights exemplary ESCO projects in Germany (“Contracting” is the German word for Energy Service Contracts). For the first time since the launch of the awards in 1997, the jury members from the magazine Energy & Management and the German Heat & Power Association, AGFW, presented one of these awards to a solar thermal ESCO. On 16 April, Christian Holter (third from left), Managing Director of Austrian turnkey system supplier S.O.L.I.D., was presented with the second prize for its solar energy supply contract with a district heating company in the Austrian city of Graz. The company published Tech Sheets and Fact Sheets about ESCO models as part of the IEA’s Solar Heating and Cooling programme’s Task 45, Large Scale Solar Heating and Cooling Systems (see the attached documents).

Enertracting, located in Kassel, Germany, offers solar heat as an Energy Service Company (ESCO). Its first flagship project has been a gas pressure regulating system, for which the company presented some financial and operational data at a workshop organised by the Thuringian Ministry of Economy, Employment and Technology in Erfurt in June 2014. The project, which is located in the town of Großseelheim in central Germany, has a fixed 15-year heat price of 55 EUR/MWh, which allows for a 7 % benefit for the investor (in this case, Enertracting) and a payback period of seven years. The key factors: a required temperature of between 20 and 40 °C, as well as a 30 % subsidy by the German KfW banking group.
